    Notes: The management of primary sclerosing cholangitis (PSC) is hindered by incomplete understanding of the pathogenesis of the disease and the lack of good prognostic models. Few large randomized controlled trials of drug therapy have been published. Best practice in the management of PSC is currently based therefore on careful interpretation of the available evidence, close observation of individual patients and clinical experience of the disease. Drug therapy is useful for alleviating symptoms. Ursodeoxycholic acid may slow progression of the disease and reduce the frequency of complications. Consensus is emerging on the issues of screening for the malignant complications of PSC and the indications for liver transplantation are becoming broader and encompassing the earliest stages of cholangiocarcinoma. In view of the rarity of the disease in the general population, large international collaborations to study PSC are necessary to provide clearer answers in areas of uncertainty, and these are now beginning to emerge.

    Notes: [Auszug] Four strains of A. tumefaciens were examined. Two strains, IIBV7 and C-58, are virulent and have been shown to harbour a large plasmid which is associated in some way with virulence8. The other two strains IIBNV6 and NT1, are avirulent and do not contain the plasmid. Strains C-58 and NT1 are very ...

    Trace enrichment of cytokinins from Douglas-fir xylem extrudate (1976)
    Springer
    Planta 131 (1976), S. 271-274 
    Details
    ISSN: 1432-2048

    Topics: Biology
    Notes: Summary Quantitative trace-enrichment of cytokinins from a plant source (xylem sap from the Douglasfir, Pseudotsuga menziesii (Mirb.) Franco) has been achieved by adsorption onto octadecyl-silica columns followed by elution with ethanol. Adsorption is rapid and efficient and allows complete recovery of cytokinins at the nanomolar level. Douglas-fir sap contains at least four compounds having cytokinin activity, one of which co-elutes with zeatin and another with ribosylzeatin.
